If your GoHighLevel emails land in spam, the fix is usually setup, not content. Send from a dedicated subdomain you own, authenticate it with SPF, DKIM and DMARC, include a one-click unsubscribe, keep your list clean and ramp up volume gradually. Gmail and Yahoo require authentication and easy unsubscribes from bulk senders, so skipping these steps hurts every email you send.

| Fix | Why it matters |
|---|---|
| Dedicated sending subdomain | Separates your marketing reputation from your main domain |
| SPF and DKIM | Prove you're allowed to send for your domain |
| DMARC | Tells inbox providers how to handle unauthenticated mail |
| One-click unsubscribe | Required by Gmail and Yahoo for bulk senders |
| Clean list | Remove bounces and long-inactive contacts |
| Gradual warm-up | Increase volume slowly on new domains |

Purchased lists destroy sender reputation.
Plain, useful emails beat heavy designs and spammy phrases.
Keep spam complaints very low; stop sending to people who don't engage.
Send to a few test inboxes first.
Usually missing domain authentication (SPF, DKIM, DMARC), sending from a shared or new domain without warm-up, or a list with bounces and inactive contacts.
It's strongly recommended, so your marketing reputation is separate and authenticated.
Bulk senders need authentication, DMARC, an easy one-click unsubscribe and low spam complaints.
Start with small volumes to engaged contacts and increase gradually.
